If there are used in the manner described under (a), instead of 250 g (1 mol) of 3,12-diisopropyl-1,2-diaza-1,5,9-cyclododecatriene, 61 g (0.2 mol) of 3,12-di-(2-pentyl)-1,2-diaza-1,5,9-cyclododecatriene (diastereoisomeric mixture) and correspondingly reduced amounts of catalyst and solvent, using otherwise the same procedure, there is obtained, as the main fraction, 48.4 g (77% of theory) of 5,14-diamino-4,15-dimethyloctadecane in the form of colourless oil [b.p. 155°-159° C./0.03 Torr; nD20 =1.4632; IR (liquid) inter alia bands at 3246, and 1613 cm-1 ].
